Thanks for that info, it saves me some time. This is a new area for me
though: do you redirect stdout on the server to a socket and have the
client listen and somehow pipe the sockets contents to the client
stdout?

Interestingly, the RPYc package manages it--that is, the client gets
the stdout of the server process, so I'll dig into that code to get an
idea. In the meantime, are there any recipes or other docs that would
be helpful? I've been googling but without much luck.

thanks,
